Is Squidoo a good earning site?

Hello, I have a friend that wants me to join squidoo under me. :) I have heard that you are meant to write articles that aren't long. Is it a reccommended site for me to join? Or does only a few very successful article writers get all the money and every one else doesn't get anything?
Any information will be helpful, because I really want to help my friend out, but I don't know if it is worth it. I've asked for information from him too, but he hasn't replied yet, so I thought I should try out mylot.

I don't know hot to make money there. I have two lens. I have one lens that have about 800 visitors but I haven't get any money. I don't know how it work. I don't know how we can get money here. What I know is, make lens and make good articles. Just ask in Squidu Forum.
